Title: Method and apparatus for converting color component type of picture signals, method and apparatus for converting compression format of picture signals and system for providing picture signals of a required compression format
Inventor: UENOYAMA TSUTOMU
IPC: H04N19/61
Filed: 1998-02-26
Abstract: In this picture signal converting apparatus, digital picture signals compressed in a DVC format are decoded to non-compressed picture signals of a 4:1:1 color component type which are composed of color difference signals and luminance signals. The color difference signals of the 4:1:1 color component type arranged in a matrix are removed on every other row to halve the number of color difference signals in a y direction, and a color difference signal is added to a position between each pair of color difference signals adjacent to each other in an x direction to double the number of color difference signals in the x direction. Therefore, converted color difference signals of a 4:2:0 color component type are produced from the color difference signals. Values of the converted color difference signals are determined according to values of the color difference signals.          Thereafter, the converted color difference signals and the luminance signals of the non-compressed picture signals are combined to produce converted digital picture signals of the 4:2:0 color component type.

Patent CA-2242565-A1 (CA)
Inventor: LUHM RALPH
IPC: F16B13/04
Filed: 1997-01-09
Abstract: A temporary fastener (10) that fastens two adjacent workpieces (40, 42). The fastener includes a shank (12) that extends through a hole of the workpieces (40, 42). Extending from one end of the shank is a conical shaped head (20).  The fastener also contains a pull stem which has a head (28) located adjacent to the blind end of the shank. The stem head (28) is pulled through the shank (12) to expand and tightly fasten the shank (12) to the workpieces (40, 42).  The fastener is removed by drilling through the head and the shank. The diameter of the conical shank head is smaller than the diameter of the drill bit (54) so that part of the head (20) does not become attached to the drill bit and scratch the workpiece (40). The conical shape of the head also reduces the volume of the fastener material to further reduce the size and amount of chips produced during the drilling process. The tightly engaged shank prevents the fastener from rotating during the drilling operation.

Title: Emergency shutoff valve exerciser for steam turbine and methods for installing and operating same
Inventor: TYE RANDY G
IPC: F16K31/56
Filed: 1998-10-19
Abstract: An apparatus for exercising an emergency shutoff valve of a steam turbine manufactured by Elliott Co., frame sizes AYR, BYR, BYRH, BYRHH, CYR, DYR, and E-Line turbines with standard Elliott Trip systems and methods for installing and operating the same. A frame of the apparatus mounts on top of an emergency shutoff valve body and spans the axis of a valve stem of the emergency shutoff valve. A plunger is suspended from the frame and connects to the top of the valve stem of the emergency shutoff valve. The emergency shutoff valve, which is biased to spring closed, is held in place by the apparatus. With the valve thus secured, the tripping mechanism for the emergency shutoff valve can be disconnected from the valve stem and exercised, tested, or serviced. Additionally, the valve stem can be moved or exercised to assure its operability and to dislodge deposits or corrosion from the valve stem. Movement of the plunger is limited by retainer means that restrict movement of the plunger relative to the frame. By this arrangement, the valve stem can be exercised through a predetermined range of motion without risk of substantially interrupting the flow of steam through the emergency shutoff valve. Where practical, the emergency shutoff valve exerciser is preferably stainless steel, which has enhanced corrosive-resistant properties. The apparatus thereby extends the uninterrupted service life of the emergency shutoff valve by insuring the operability of the valve and providing means for maintaining the valve and other related components without shutting down the steam turbine.

Title: Electronic refrigeration unit temperature alarm
Inventor: VIDAILLAC PIERRE
IPC: F25D29/00
Filed: 1998-12-17
Abstract: An electronic freezer thermometer alarm computes an estimation of contents temperature in a freezer from the freezer air temperature. The calculated contents temperature is displayed by a LCD display and is used to trigger a sound alarm, by use of a piezoelectric buzzer, in case of too high a value. Alternatively, the freezer air temperature is used to start a timer that triggers the alarm several minutes after the freezer air temperature have risen above the limit value. In this case, the displayed temperature is the freezer air temperature. In both cases, freezer air temperature acquisition is done by the resistance measurement of a thermoresistor placed into a small case constituting the temperature probe. The thermometer housing has two magnets to keep on freezer external surface. The temperature probe is connected to the housing by a small thickness of wire going under the freezer door gasket. The thermometer is energized by a lithium battery placed into the case The housing encloses a printed circuit board on which are off-the-shelf electronics components.
